Abstract: Trusted computing is an active defense and immune security system. In this paper, from practical demands in financial industry and electronic government, we propose a cryptographic service platform based on trusted computing, which supports domesticallymade standard SM1, SM2, SM3, SM4 cryptographic algorithms and uses trusted computing technology to protect cryptographic deices and systems. This platform provides uniform cryptographic computing service, key management and cryptographic devices management etc, and it has excellent reliability, security, efficiency, parallel processing and load balancing. This platform can be applied to financial industry, electronic government and electronic commerce.

Key words: trusted computing, cryptographic technology, public key cryptosystems, symmetric key cryptosystems, cryptographic hash algorithms
